Your HRV is 12% below your 7-day baseline and you slept light. Let's swap today's threshold session for an easy 40 minutes. The hard work moves to Thursday.

Connect. Check in. Train.

1

Connect your watch

Link your Garmin, Apple Watch, or COROS. BCKLE pulls your training, sleep, and recovery data automatically -- no manual logging.

2

Check in each morning

A 30-second check-in combines how you feel with what your body data says. Your readiness score tells you whether to push, ease off, or rest.

3

Train with a plan that listens

Your plan adapts around your readiness. If today's intervals don't make sense, the plan adjusts -- the hard session moves, it doesn't disappear.

One number. Every morning. Before you train.

Your readiness score combines your heart rate variability, sleep quality, training load, and how you actually feel -- into a single number that tells you what today should look like.

It's not a grade. It's context. A low score doesn't mean you failed -- it means your body is asking for something different today. A good coach would spot this. BCKLE does the same thing, with your data.

Heart rate variability

Your overnight HRV, tracked against your personal baseline -- not a population average. Trends matter more than any single reading.

Sleep

Total duration plus quality. Short sleep or poor deep sleep shifts today's plan toward recovery -- before you dig a deeper hole.

Training load

Acute vs chronic workload ratio. Climbing too fast? BCKLE catches it and pulls the session back before injury risk rises.

Body signals

Log a sore calf or heavy legs in your morning check-in. BCKLE routes around it -- adjusting intensity and flagging recurring patterns.

Runners and triathletes who want to train smarter.

5K to Ironman. If you've ever pushed through a session your body wasn't ready for -- and paid for it later -- BCKLE is for you.

Building toward your first race

A plan that adapts when life gets in the way. Clear daily guidance without the jargon or overwhelm. You don't need to know what HRV means -- just follow today's session.

Chasing a PB

Training load monitoring, recovery tracking, and taper guidance so you arrive at the start line ready. Not worn out. Not undertrained. Ready.

Balancing three disciplines

Swim, bike, run -- each with different recovery demands. BCKLE schedules sessions across all three, respecting how yesterday's ride affects today's run.

Coming back from injury

Gradual load progression with daily readiness checks. The plan holds you back when it should and builds you up when you're ready.

One plan. Everything included.

Adaptive training plans, daily readiness, session-specific fuelling guidance, niggle tracking, race preparation, and smart taper -- all in one place.

No tiers. No feature gates. No upsells. The full experience from day one.
